KMG Grinder Questions

Loneronin, I thought so, too. I should really have used change-over (rotary cam) switches, but they were too pricey to make it feasible. The switches I'm using are 3-pole screw posts (3PST) and they are rated for well above the Amps at 220V that the VFD puts out. Just make sure you have them wired so that it is impossible to send current to two different motors at the same time (that will fry your VFD). The way mine is set up, the first switch sends power to my KMG or to the second switch. The second switch selects my disc grinder or my EERF grinder. At no time can current be going to two different motors. I always wait until the VFD is electrically silent (no output) before throwing the switches.
